Abstract
The process comprises reaction of acid with a co-haloalkanoic acid ester. To increase efficiency, the acid has the formula (I) and the derivs. have formula (II) where X,R,R1 and R2 can be various radicals. The reaction employs an inert organic solvent and, in the presence of an alkaline carbonate or a tertiary amine, takes place at a temp. between 20 deg.C and the b.pt. of the solvent.
